AB  - PURPOSE: To investigate the within-session reliability of bilateral- and 
      unilateral-stance isometric midthigh-pull (IMTP) force-time characteristics 
      including peak force (PF), relative PF, and impulse at time bands (0-100, 0-200, 
      0-250, and 0-300 milliseconds) and to compare isometric force-time 
      characteristics between right and left and dominant (D) and nondominant (ND) 
      limbs. METHODS: Professional male rugby league and multisport male college 
      athletes (N = 54; age, 23.4 +/- 4.2 y; height, 1.80 +/- 0.05 m; mass, 88.9 +/- 12.9 kg) 
      performed 3 bilateral IMTP trials and 6 unilateral-stance IMTP trials (3 per leg) 
      on a force plate sampling at 600 Hz. RESULTS: Intraclass correlation coefficients 
      (ICCs) and coefficients of variation (CVs) demonstrated high within-session 
      reliability for bilateral and unilateral IMTP PF (ICC = .94, CV = 4.7-5.5%). 
      Lower reliability measures and greater variability were observed for bilateral 
      and unilateral IMTP impulse at time bands (ICC = .81-.88, CV = 7.7-11.8%). 
      Paired-sample t tests and Cohen d effect sizes revealed no significant 
      differences for all isometric force-time characteristics between right and left 
      limbs in male college athletes (P >.05, d </= 0.32) and professional rugby league 
      players (P > .05, d </= 0.11); however, significant differences were found between 
      D and ND limbs in male college athletes (P < .001, d = 0.43-0.91) and 
      professional rugby league players (P < .001, d = 0.27-0.46). CONCLUSION: This 
      study demonstrated high within-session reliability for unilateral-stance IMTP PF, 
      revealing significant differences in isometric force-time characteristics between 
      D and ND limbs in male athletes.
